On Oct. 12, 1989, some Chinese scientists were working at the computers to look for the information they needed. Suddenly they saw a lot of very bright spots crossing the computer’ s screens. At the same moment the computers were working much slower. To find out what was happening, they stopped their work to check some parts of the computers. To their horror, they found out that most of their stored information was got rid of by computer viruses (病毒). Obviously all these computers had been infected (传染) by computer viruses.
It is said that the computer viruses were made by a group of young men fond of playing tricks. They all have excellent education. They created the viruses just to show their intelligence. This kind of computer viruses are named Jerusalem (耶路撒冷) Viruses. These viruses can stay in computers for a long time. When the time comes the]/ will attack the computers by lowering the functions, damaging normal programs or even getting rid of all the information.
We now come to know that Jerusalem Viruses often attack computers on Fridays and that they are spreading to a lot of computers. Among the countries that suffered computer viruses last year are Britain, Australia, Switzerland and the U.S. But till now, how to get rid of the terrible viruses remains a problem.
According to the passage, which of the following is true?
选项
A、Scientists have found a way to get rid of the viruses.
B、The Jerusalem Viruses are a great harm to human’s health.
C、The viruses will come to a new computer after staying in the old one for some time.
